Thor, or should that be Zeus?

Chaz I am afraid that the choice has to be yours alone. Are you using it to hold threading rod in a hole or bolt anchors?

I have 2 requirements. The first is to hold M12 nuts in place that allow me to tighten the bolts holding the rails in place.

Secondary is similar where ill either sink nuts for holding and mount hardware the same way (motor mounts etc) or where Ill epoxy thread bar in place. My preference is to sink the nuts so I can use bolts from the top.

I don't think you will have enough purchase with the nuts as they might pull out, also think about getting epoxy in the threads and the bolt will have to go right through the nut into some pocket or other. If you look at the chart on the http://www.ebay.co.uk/itm/ANCHORSET-...c=1&rmvSB=true

it shows how deep the hole should be for a 10mm rod

Re the colour I have to pass but you could phone Sika up and ask their techy guys.

Thanks. For my current epoxy I was drilling a 30mm hole which is a pain in the ass but allows full cover to the top and sides of the M12 nut.

IVe ordered one of each, will try them and see.

Main gantry poured, will post pics later.

Used a bit less plastisizer this time. 950ml per 25kg of cement. I tried with the minimim recommended amount of 500ml but not enough water so the mix was really tight.

Wow, 3 months have gone, I am piss poor at keeping this thread updated.

So gantry was done, Y motor mounted, some test movement here:-

Ignore the last 100mm or so that is unsupported. Long story, That will be epoxied it later.

A pic of how it all looks, my wife not happy with me taking pics of her. Testing the fit before I attempt to epoxy this lot together.
